Steno attenuatus, Cfray, Zool. Ereh. ^ Terr. p. 44 (1846). 



This name is retained at present for a series of specimens closely 

 resembling the last group, but with a more slender rostrum and 

 with the teeth slightly smaller and more numerous. 



Though single well-marked specimens of Gray's Clymenia doris 

 and Steno attenimttis may be so unlike as to justify their being 

 placed in distinct species, yet when a large series, such as those of 

 the British Museum and College of Surgeons combined, are compared 

 together, the two extremes pass so insensibly into each other that it 

 is impossible to say where one begins and the other ends, and it is 

 diflcult to avoid the suspicion that the differences depend upon age, 

 or sex, or on individual variation. Unfortunately these forms are 

 known at present only by skulls. When the remaining parts of their 

 organization can be correlated with them, probably other specific 

 distinctions wiU be demonstrated.
